dont waste time, get started modding modding, whats a warranty worth neways? its a honda. ive got an 06 SI coupe w/ X intake, DC race header, skunk2 70mm exhaust, Hondata reflash, TWM SS, P2r throttle body spacer, Hondata intake manifold gaskets, Ray's Eng. G-games 77w 2 piece wheels, Eibach Sportlines, Skunk2 Camber arms, 6000k HID kit, ect. The Hodnata reflash was by far the best mod to date. Lowered vTAKKK engaugement to 4.5k rpms and redlines and makes power all the way up to 8600rpm. Wait until you get a few bolt ons first though for best results. There is a fair ammount for us out already but not so much for the 4dr yet. There arent any solid tuning options out there yet due to the drive by wire and MAF sensor. As soon as my tax return gets here im going comptech STG I supercharger... I live in Kennesaw so hit me up if you wanna check it out.

also 8thcivic.com is the new civic forums lot of useful info there.

Thanks,
Josh
